MINE-CAR.

No. 926,446. Specification. of

Application lcd October 29 To all whom it may concern:

Be it kn own that we, THOMAS W'. VnAvER and CLYDE B. Nnavna citizens olthe United States, and residents ot 'l`unnelton, in the county otPreston and State ot' 'West Virginia, have invented new and usefullmprovements in Mine-(lars, of which the Aliollowing is a full, clear,and exact description.

This invention relates to improvements in mine cars, and moreparticularly such as dumping cars or the like, and cach of which ingeneral is provided with a trigger, a locking member adapted to engage acatch to hold the end gate or door ol' a car normally in a closedposition, and a movable link connecting the trigger an d the lockingmember, means being provided whereby the trigger can be actuated torelease the locking member vfrom the catch.

The object ot the invention is to provide a device of the classdescribed, simple and serviceable in construction, which will securelylock the end gate of a ear, and which will be automatically releasedwhen the car has reached a predetermined point, so that the contents ofthe car will be easily discharged.

Reference is to be had to the accompanying drawings forming a part ofthis specilication, in which similar characters of reference indicatecorresponding parts in both views.

Figure 1 is a perspective view showing an embodiment of our inventionapplied to a mine car; and Fig. 2 is an enlarged. perspective viewshowing our invention in detail and with the gate closed.

In the speeiiic form shown in the drawings, 1 represents a car of anycommon or preferred form, having an end gate 2. Extending around the endof the car and being substantially U-shaped in form, is an elongatedstrip 3, the latter having its ends 4 extending above the upper edge ofthe car. The ends 4 have openings 5 extending therethrough whichconstitute bearings adapted to receive the ends oi' a support 6,preferably circular in cross section. Cotter ins 7 serve to secure thesupport at the endjs 4 of the elongated strip.

Located on the gate 2 are members or straps 8, the latter having theirupper ends 9 curved over the support 6, so that the latter will movablycarry the gate. Arranged on the outside of the end gate is a bracket 10Letters Patent. Patented June 29, 1909.

having outwardly disposed extensions 11 provided with registeringopenings 12. Pivotally secured between the extensions 12 by means o'l apin v13 is a trigger 1-1, preferably in the lorm. o'l a bell cranklever, and having its upper end 15 extending above the support 6. Thelower end 16 of this trigger is outi Tardly disposed and bi'l'urcated,as shown most clearly in Fig. 2 ot the drawings.

Slidably secured to the gate is a link 17 having its upper portion 18outwardly disposed and terminating between the bifurcated ends 1.6 olthe trigger, where it is pivotally held by means of a rivet or pin 19.Guides 20, secured to the gate, serve to hold this link in place. Thelower end 21 ol the link is cut away and broadened to lorm a foot.Located on the link near the lower end thereof, is an extension 22having an opening extending therethrough Pivotally secured at thisextension by means el a rivet 28 or the like, which extends through itsupper bifurcated portion, is a locking member 24, Secured to the loor ofthe ear is a catch 25 which has its outer end 26 upwardly disposed andadapted to receive the lower end of the locking member 241, so that theend gate of the car will be held against accidental displacement.

Located at any suitable point adjacent to the track is a stop 27, whichis adapted to engage the upper end 15 of the trigger to actuate the samewhen the ear has reached a predetermined point, at which its contentsare to be discharged, as illustrated in Fig. 1 of the drawings.

In the form shown, the stop is secured to the frame of a building andextends downwardly therefrom. Jhon the trigger' has come in'contact withthe stop, it is so actuated that through the medium of the link 17, thelocking member 24 is drawn out of engagement with the catch 25, and theend gate, against which constant pressure is being brought to bear bythe weight of the contents of the car, will swing open and permit thedischarge of the same.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent:

1. In combination with a mine car, a catch on the ear a swinging endgate, a link slidably mounted on said end gate, a trigger pivotallysecured to said link and said gate, and a locking member pivotallycarried by said link and adapted to engage said catch to hold said gatein a locked position.

2. In combination With a mine car, a Catch on the oar a swinging endgate, a link slidably mounted on said end gate, a trigger pivotallysecured to said link and said gate, and a locking member pivotallycarried by said link and adapted to engage said catch to hold said gatein a locked positionJ and means adapted to engage said trigger foractuating the same whereby said gate Will be released to permit thedischarge of the contents of the ear.

3. In a mine ear provided With a swinging
